| 目的 了解肝包虫囊肿手术摘除后肝脏形态的变化特点。 方法 对344例B超诊断并经手术病理证实的肝包虫囊肿术后肝脏的超声图像特征进行了分析研究。结果 术后肝脏形态变化取决于术前肝包虫的部位和大小:一般右肝包虫引起肝右叶缩小或消失,肝左叶再生增大;左肝包虫则肝左叶缩小或消失,右肝再生增大。往往包虫越大,萎缩与再生就越明显。肝脏的萎缩与再生是在包虫生长过程中形成的,术后肝脏的形态结构将不会再改变。 结论 肝包虫囊肿是肝脏的良性占位性疾病,不管包虫多大,压迫多么严重,部分肝叶总能通过再生保持正常的肝脏体积和肝脏功能,术后肝脏形态的变化就清楚地说明了这一点。 |

| Objective To learn the characteristics of liver morphologic change after operation on liver hydatid cyst diseases. Methods A study was made on the features of ultrasonic images of postoperative liver morphosis of 344 patients with liver hydatid cyst diagnosed by ultrasound and confirmed by operation and pathology. Results The liver morphologic change after operation depended upon the localities and size of the cysts before the operation. Generally,the right liver cysts caused the atrophy or disappearance of the right liver lobes and regeneration of left lobes,while the left liver cysts led to the atrophy or disappearance of the left liver lobes and regeneration of right lobes.The bigger the cysts,the more obvious this kind of phenomena.The atrophy and regeneration were formed during development of the cysts,so there would be no longer any changing taking place in the postoperative liver morphosis. Conclusion Liver hydatid cyst is one of the benign space occupying lesion in liver.No matter how big of the cysts or how severe of its pressure to the liver tissue is,the amounts of the liver cells and the liver functions can always be kept in normal condition by the regeneration of partial liver lobes. It can be clearly indicated by the change of postoperative liver morphology. Ultrasonic diagnosis; Liver hydatid cysts; Liver atrophy and regeneration 在B超诊断工作中,我们发现几乎所有肝包虫囊肿病例在包虫摘除术后其肝脏形态结构均发生明显变化,这种变化显然与包虫引起的部分肝叶萎缩及部分再生有关。为此,从1995年至2001年我们对肝包虫囊肿引起肝脏再生及术后肝脏的形态变化等问题进行了深入的研究。 1 材料和方法 本文344例肝包虫囊肿术后患者中,男153例,女191例。年龄6~76岁。术前包虫直径均在5cm以上。全部病例术前均由B超诊断, 经手术病理证实并有肝功能检查记录。术后各进行一至数次B超复查。仪器为东芝SSA-240A型和Aloka-1000型B超诊断仪,探头频率3.5MHz。肝脏常规扫查,对包虫病例详细观察记录包虫的数量、大小、位置、肝脏各叶的大小和形态并拍片存档。对每一病例进行手术、病理及肝功能检验结果的随访记录。术后进一步B超检查,记录肝脏的形态结构变化。对资料完整且无肝炎、肝肿瘤、胆道梗阻及因其他原因引起的肝脏形态及功能异常的病例资料进行整理分析。 2 结果 2.1 344例均有肝脏形态结构改变 表现为部分肝叶缩小同时部分肝叶增大,其中右肝各叶完全消失伴左肝各叶增大(图1)65例; 右肝各叶及左肝内叶完全消失,左肝外叶异常增大(图2)12例;右肝一叶消失,一叶缩小,伴左肝各叶增大图1 右肝包虫术后,右肝各叶消失,左肝各叶增大,门脉左支矢状部内径增宽达1.8cm GB:胆囊;LEL:左肝外叶;LIL:左肝内叶;LPV:门脉左支矢状部 图2 右肝前叶巨大包虫术后,右肝各叶及左肝内叶消失,左肝外叶增大伴管道结构增宽 图3 右肝后叶包虫术后,右肝后叶消失,右肝前叶缩小,左肝各叶增大 LL:右肝(前叶);LP:门脉左支矢状部 图4 左肝包虫术后,左肝各叶消失,左肝各叶增大,RAL:右肝前叶;RPL:右肝后叶 图5 左肝内叶包虫术后,左肝内叶消失,左肝外叶缩小,右肝各叶增大 图6 左肝前叶及左肝内叶包虫术后,右肝前叶及左肝内叶消失,右肝后叶及左肝外叶增大 |
